Pentek increases recording rate for Quartz RFSoC products
Extending the Talon series of recorders, Pentek has added the Model RTR 2757 4U 19-inch rackmount recorder. It complements Pentek’s Quartz RFSoC products that stream digitised wide bandwidth signals across 100GbE. The RTR 2757 can capture these streams in real time at up to 12.5Gbytes per second.
The RTR 2757 was designed for rugged environments. It includes up to 122Tbyte of non-volatile memory express (NVMe) storage, using high-performance NVME U.2 drives in a RAID0 configuration to provide high-speed real-time recording. Drives are front-panel removable via eight individual drive trays. The independent OS drive is can also be removed via the front panel. This architecture improves the recording speed by fifty per cent over previous generations of Talon recorders, reports Pentek.
The industrial grade 4U rackmount chassis of the RTR 2757 houses a dual Xeon server class motherboard. A single QSFP28 optical port supports up to four independent UDP streams for a combined real-time recording rate up to 12.5Gbytes per second or 100Gigabits per second. This allows users to stream data from four of the RFSoC’s A/D channels over 100GbE and capture them as independent files on the recorder. The recorder captures only the Ethernet payload, providing data files similar to other Talon recorders and compatibility with the SystemFlow signal analysis tools.
All Talon recorders are built on a Microsoft Windows platform and include Pentek’s SystemFlow software, featuring an intuitive graphical user interface (GUI) which uses point-and-click configuration, the Signal Viewer and application programming interface API).
The Signal Viewer provides a virtual oscilloscope and spectrum analyser to monitor signals before, during and after data collection. The C-callable API allows users to integrate the recorder control into larger application systems. The data format used for storage follows the NTFS standard, allowing users to remove drives from the instrument and read the data using standard Windows-based systems, eliminating the need for file format conversion.
A Talon Recording System Simulator is provided as a free trial for evaluation of the SystemFlow software package.
